I see what you guys mean, I understand that sense of - "he's a CB, let him focus on that; and let us have a clear CB hierarchy and depth". But then - we rely on another FB as cover for CB anyway. And we do play him at RB sometimes. What would we be losing if he played at RB, if indeed we consider him to be the first choice there, and then play him as a CB (and introduce his back up, Debuchy or even Bellerin) if something happens toper/Kos. We'd be losing -
Fatigue factor; added injury risk. O stuff like that.
But that seems to me a bit confused:
- you'd be intentionally choosing lesser players to play for the idea of what might be, and
- you can always change for added considerations.
But that is different from declaring your first 11 is such that it doesn't really introduce the first 11.
Again - the conclusion is not necessary, but the reason, the consideration in favor of playing him is certainly there.
